Package arrived on time. There was some damage/dents in a couple of the 4 corner posts.
Assembly was somewhat complicated and took both time (a couple hours) and patience. Adding numbers to the diagrams to indicate the sequence of steps would be helpful and save time. Although the diagrams were detailed and pictures clear, patience were required to determine which steps to take first. 
Definitely requires 2 people to physically assemble this pergola.  In addition, an extra person to interpret the directions/diagrams was helpful.
My family and I have really enjoyed this elegant pergola. The lovely canvas cover slides easily and stays put when locking screw is tightened. We live on a creek draining the largest lake in California and the wind can be stiff and pick up in a moment. This pergola has held up well so far in mild wind. We have yet to experience a stiff breeze and plan to pull it to one side when that happens. We have it screwed down to the deck.
